screens do not keep out all the flying insects, which always seem to hang around my face. this is an ideal tool. zaps them dead, eventually. works well and quite satisfying to get rid of the annoying flyers.

The bug zapper was a God send for our cabin vacations in the woods and our houseboat. Other electric zappers could hurt the precious bees. But, I love to swat all other flying bugs. My grand kids love it too. For all of us, it is a fun activity. I'm buying my third one as I gave my last one to friends, who saw the kids and my success in making our outdoor dinner bug free. It is a marvelous invention; an improvement over the common fly swatter. Just swing the racket through the air and look for the electrical spark and burn smell. It means success.
